Ignorance is commonly assumed to be a lack of knowledge in Plato’s Socratic dialogues. I challenge that assumption. In the Protagoras, ignorance is conceived to be a substantive, structural psychic flaw—the soul’s domination by inferior elements that are by nature fit to be ruled. Ignorant people are characterized by both false beliefs about evaluative matters in specific situations and an enduring deception about their own psychic conditions. On my interpretation, akrasia, moral vices, and epistemic vices are products or forms of (...) ignorance, and a person who lacks knowledge is not necessarily ignorant. (shrink)

In the 'Hippias Major' Socrates uses a counter-example to oppose Hippias‘s view that parts and wholes always have a "continuous" nature. Socrates argues, for example, that even-numbered groups might be made of parts with the opposite character, i.e. odd. As Gadamer has shown, Socrates often uses such examples as a model for understanding language and definitions: numbers and definitions both draw disparate elements into a sum-whole differing from the parts. In this paper I follow Gadamer‘s suggestion that we should focus (...) on the parallel between numbers and definitions in Platonic thought. However, I offer a different interpretation of the lesson implicit in Socrates‘s opposition to Hippias. I argue that, according to Socrates, parts and sum-wholes may share in essential attributes; yet this unity or continuity is neither necessary, as Hippias suggests, nor is it impossible, as Gadamer implies. In closing, I suggest that this seemingly minor difference in logical interpretation has important implications for how we should understand the structure of human communities in a Platonic context.

This paper attempts to determine what laws’ most fundamental normative property is for Plato. After examining the Hippias Major and the pseudo-Platonic Minos, I argue that in the Laws this property is correctness (orthotês) which is understood as maximizing the citizens’ happiness. I argue that laws failing to do so are defective as laws because they’re not partially grounded in the relevant ethical facts and that Plato is thus a natural law theorist. The last section provides further justification for the (...) claim that laws failing the correctness criterion are defective as laws by appealing to Plato’s understanding of practical rationality.

I discuss Aristotle’s opening argument against Platonic Forms in _Metaphysics_ A.9, ‘the Razor’, which criticizes the introduction of Forms on the basis of an analogy with a hypothetical case of counting things. I argue for a new interpretation of this argument, and show that it involves two interesting objections against the introduction of Forms as formal causes: one concerns the completeness and the other the adequacy of such an explanatory project.

The proverb “chalepa ta kala” (“fine things are difficult”) is invoked in three dialogues in the Platonic corpus: Hippias Major, Cratylus and Republic. In this paper, I argue that the context in which the proverb arises reveals Socrates’ considerable pedagogical dexterity as he uses the proverb to rebuke his interlocutor in one dialogue but to encourage his interlocutors in another. In the third, he gauges his interlocutors’ mention of the proverb to be indicative of their preparedness for a more difficult (...) philosophical trial. What emerges in the study of these three Platonic dialogues is that Socrates believes that how he and others describe learning makes a tangible difference in philosophical investigation. (shrink)
